“I used this during a hike in Hawaii and the strap is a little too thin and could use some padding in the shoulder area. I ended up carrying it for the last half of the hike because the strap was digging into my shoulder too much.”
“I bought this since I have a few of these 40oz tumblers and I use it for work, in case I need to have my hands free using this sling helps and there is a pretty good size zipper pocket and outside for convenience I've used it to hold my phone and other small items.”
